Abstract
Large scale linear structures of the topography, clearly seen by aerial and satellite imagery and commonly referred to as lineaments, attract close attention for more than a century, and their relation with the subsurface structure is recognized and widely investigated. The lineament analysis techniques can be a method for express assessment of the tectonic structure including primary tectonic zonation of the terrain. A simple method for such analysis includes manual or semi-automated processing of DEM (digital elevation models) derived from satellite images, extracting lineament structures and statistical analysis of their orientations. It is shown, that such rose diagrams display common features for different tectonic situations with dominant lineament directions along regmatic network, but the differences of the diagrams can be a tool for primary geomorphological snap analysis of the terrain, such zonation closely matching the differences in actual tectonic setting.
